GROUND WATER

         OCNED is also specializing in drilling for exploration , development and management for groundwater supply. We have   

         involved in numerous projects in Malaysia for groundwater supply for domestic, industrial and construction utilization. Hence,

         we have the experience in assisting to gather information required for LUAS application for approval to extract groundwater use.

         Lembaga Urus Air Selangor (LUAS) have named Ocned Water Technology Sdn Bhd in their panel as a company to supply

         for approval to extract groundwater for utilization in the Selangor State. Under Selangor Waters Management Enactment 1999,

         Lembaga Urus Air Selangor is a board to manage the water supply be it from underground source or surface source.

         Section 45 of enactment 1999 for groundwater utilisation is as follows :-

                         - The rights to water for substance agricultural / domestic purpose.

                         - The right conferred in subsection (2) may be exercised provided that any works for taking and using the water

                           does not :-

                         a)   cause a significant obstruction or diversion to the flow of water in the water source;

                         b)   store more than mega litre of water or such other quantity as may be declared or determined by the Authority

                               time to time;

                         c)   take water from the eater source at a rate of flow exceeding 20 litre/sec or at such other rate as may be declared

                               or determined by the Authority from time to time

         Section 107 - Any person using water from either source without LUAS approval be be fined not more than RM100,000 or

                              Jailed not more than 2 years or both.

         We offer application service to any customer having tubewell/tubewells constructed by us or by others. Our charge is reasonable    

         depending on the available tubewell/tubewells record that the customer may have.

         Groundwater Supply

         There are two sources for water supply available to man, namely :-

         SURFACE source which includes rainfalls, lakes, streams, drainage areas that funnel water toward holding reservoirs and

         catchments

         GROUND source which includes wells, springs and horizontal galleries.

         The world's liquid asset consists of :-

         a)  97.3% as saline water in Ocean

         b)  2.1% as solid water in Ice Caps and Glaciers

         c)  0.6% as liquid fresh water n Underground, Rivers and Lakes

         Of the 0.6% fluid fresh water available at any given moment on our planet earth, rivers and lakes hold 0.01% and underground

         water holds 0.59%. Thus, more than 97% of world fresh water is available underground - an estimated of 8 trillion acre-feet.  

         Prior to carry out the Physical drilling of the water well. Our company have the expertise and equipment to carry out resistivity

         survey that can locate the best possible spot for ground water well exploration.

         ELECTRICAL RESISTIVITY SURVEYING is a geophysical propecting operation in which measurement of earth resistivity is made

         from ground surface. The relative value of electrical resistivity can be interpreted, under certain condition, in terms of the

         general geology of the subsurface to limits depths. the method have been used in ground water exploration since the early 1930s.

Figure 1 : This arrangement is the Wenner configuration for ground water prospecting

 

Various types of earth materials generally exhibit certain ranges of the resistivity values. Using four electrodes set in the ground, the apparent earth resistivity is determined by measuring the voltage drop between two interior electrodes when current is passed thought the earth between outer electrodes.  the most common arrangement is the Wenner Configuration with the electrodes equally spaced along straight line.

 

Electrical resistivity surveying finds its best application in preliminary exploration of large areas, where a substantial ground water development is desired.
